(Cl. 225-21) large size vessels inwhich the gas is to be taken up by the water. Such apparatus is open tothe objections that it is diilicult to prevent the accumulation of airin the vessel and at one or both sides of the diaphragm and that thehigh pressure of the charging'gas makes it difficult to supply freshwater to the apparatus.

An object of the invention is to provide simple and eflicient apparatus,of small size and low cost, for impregnating liquids with gas, andbottling and/or dispensing the charged liquid. An object is to provideapparatus of the type stated for supplying successive andequal volumesof water .to the charging chamber, and simultaneously discharging equalvolumes of charged water therefrom. A further object is to provideapparatus for charging liquids with gas from high pressure containers,the apparatus being characterized by a measuring chamber to whichsuccessive and equal volumes of liquid are supplied, 0 a gas-chargingchamber in communication with the high pressure gas supply, and adischarging chamber from which the charged liquid may be delivered; thethree chambers being so associat-' ed with a multiple valve that thehigh pressure in the charging chamber does not aiiect the free flow ofliquid through the three chambers. More particularly, an object is toprovide apparatus of the type stated which includes a measuring chamberin the form of a flexible or elastic bag or ball, located in a vessel,the space between the bag or ball and the vessel constituting adischarge chamber which is connected to the measuring chamber throughthe gas-charging chamber and a system of valves. A further object of theinvention is to provide apparatus of the type I stated in which thecharging chamber has the form of an elongated tube or series of tubeswhich are filled with small bodies of large total surface area, the gasinlet to the chamber being at the highest point thereof. Further objectsare to provide a venting valve system for removing air from the severalconduits and chambers of the apparatus, and to provide an outlet systempermitting the alternative discharge of the charged liquid into bottlesor into glasses and the like.

These and other objects and advantages of the invention will be apparentfrom the following specification when taken with the accompanyingdrawings, in which Fig. 1 is a view, partly in section, taken through 5the entire apparatus.

Fig. 1a is a fragmentary showing of a modification which may beintroduced into the apparatus.

of the measuring apparatus, the schematic views including sections takenon lines A-A and 3-3,. respectively, of Fig. 2; Fig. 4 showing theposition of the three-way cock in which delivery takes place, and Fig. 5a displacement of the three-way cock to the extent of in which positionthere occurs the impregnation. I 25 Fig. 6 is an axial section throughthe dismantled non-return element.

Fig. 7 is a perspective view of the apparatus ready for operation,wherein the jacket has been partially omitted to reveal the internalparts.

In the drawings a is a container, which acts as measuring and supply ordelivery vessel, and is divided 'by the rubber ball I; into an outerchamber or delivery chamber a and an inner or measuring chamber b Tofacilitate fitting 35 or exchange of the rubber ball b the casing c ofthe container a is made in two parts, whereby the detachable cap portionis pressed tightly against the fixed container portion by a peripheralsteel band 0' shown in Fig. 2, the ends 40 of which band are anchored bythreaded bolts.

41 is a double three-way cock, and servesfor actuating the measuring anddelivery device. The discharge nozzle 0, through which the impreg natedliquid is poured into a glass or a bottle, 45 is at the outlet end ofthe discharge pipe g which communicates with the delivery chamber a m isthe feed pipe for the fresh liquid, for example water, and communicateswith the interior of the rubber ball, 1. e., with the measur- 5 ingchamber b 1 is the feed pipe for the impregnating gas, for examplecarbonic acid, and opens into the impregnating pipe e filled with alarge-surface body, for example glass pearls e. The three- 55 way cockjdis actuated by the lever shown in Fig. '7, and'may be moved alternatelyinto the two positions illustrated in that figure, these positions beingdetermined by stops (not shown).

In the one position according to Fig. 4 there passes out of the pipe m(Fig. 4 at the right), which must be under pressure, fresh liquid fromthe connection 1' of the feed pipe m through the bore d of the three-waycock d into the hollow rubber'ball b this liquid filling the measuringchamber b Since at the same moment the delivery chamber a is connectedby the bore (ii of the three-way cock with the discharge pipe g (Fig. 4at the left), there prevails in this chamber merely ordinary atmosphericpressure, and the pressure in the pipe m is able to act in the ball b-For the purpose in question the rubber ball possesses a thickness ofwall amounting to 3-4 mm., and accordingly the pressure of, the liquidcauses the ball to be expanded until it thrusts against the wall of thecontainer a. In this manner the contents of the delivery chamber a areexpelled into the discharge pipe g.

If the cock is now moved into the other position according to Fig. 5,the feed pipe 1' and the discharge-pipe 9 will be closed, and thedelivery chamber a made to communicate with the measuring chamber bthrough the medium of the cock bore d theconnections h and k, the cockbore d and the impregnating tube e. The impregnating tube is under thepressure of the impregnating gas, and the latter may be as desired.

By reason of the connection established a compensation of pressure isobtained on either side of the rubber ball, and the elasticity of therubber causes the ball to contract and expel the fresh liquid containedin the measuring chamber b through the impregnating tube into thedelivery chamber 11 gas opens out into the impregnating pipe, the freshliquid carries the gas with it and assimilates the same. celerates thefine distribution and the mixing of gas and liquid. Since the quantityof fresh liquid is always equal to the quantity of impregnated liquid, adead space filled with gas is unable to form in the measuring or thedelivery chamber.

By regulating the supply of fresh liquid the impregnated liquid may beallowed to run into open receptacles without appreciable friction,pressure and speed. The impregnated liquid, however, may also be filleddirectly into bottles, in which connection, as shown, there is theconsiderable advantage that the liquid flowing out ter in the tap), andat no time under the very much higher pressure of the impregnationcontainer, so that special safety means against bursting of the bottlesare unnecessary.

In Fig. l n is a rib provided on the outer face of the rubber ball b,which rib, when the ball 'exv pands and thrusts against the inner wallof the container at, provides a free passage for the liquid.

The pipe g which connects the three-way cock d and the discharge nozzleis provided with a rapidly closing double-seated valve, the spindle p ofwhich carries at the outer end the hand-wheel u and at the inner end thepacking s which, when the spindle is screwed in, seals off the discharge'pipe 0 against the threeway cock. The spindle is passed through thespindle guide r, against which the same is sealed Since the pipe I forthe The large-surface body e acofi by the packing't also located onthespindle when the packing s is opened. q is a conical elasticmouth-piece, which is surrounded by a guard bell and is capable of beingscrewed on to the delivery pipe 0, and if the filling takes place into"bottles serves for introduction into the necks of the bottles.

In Fig. 2 there is shown the three-way cock in axialsection. The plug isdesignated d, and possesses t'wo angular bores d and d. The spaces infront of andbehind the plug within the cock casing are designated 11 and2. These two spaces communicate with each other through the by-pass x,so that a one-sided pressure is unable to take place on the plug as aresult of leaky pipes.-

As also shown by Fig. 2, the spindle d projecting out of the casingtowards the right is sealed off against the casing by a rubber washer l2which, by means of the coil spring I3, is

' pressed with its conical sealing face against the likewise conicalinner face of the threaded cap surrounding the spindle. In this manner,as shown, there is also obtained relief of the plug against axialthrust.

In Fig. 10. there is shown a reservoir a which may be disposed betweenthe impregnating tube e and inlet socket is by means of pipes a and aThe impregnated liquid does not in this case pass out of theimpregnating pipe e into'the delivery chamber a directly, but firstflows into the intermediate container a where it is held in reserve andat the same time may also' be sists of a flat rubber diaphragm 5, whichis tightly held about its circular periphery between the likewisecircular edges of two metallic cups land 3forming a casing. Each cuppossesses a central bore .and an outwardly extending socket 2 or 4'. Therubber diaphragm is also perforated at the centre, and carries a rubber.socket 6, which extends with slight clearance into the casing socket 2.In this rubber socket 6 there. is also fitted a valve, which consists ofa perforated metallic sleeve 1-, which is surrounded by a wire net, andthe end of whichdirected towardsthe rubber diaphragm is open, whilst theopposite end is closed and preferably possesses an outwardly disposedannular heading 8, against which the rubber Socket 5 can tightly engage.The casing portion carrying the socket 2 is bored at a point ll oppositethe fiat rubber diaphragm, whilst the casing portion 3 carrying theinlet socket possesses in the interior an annular groove l0 for thereception of one or more fiat metal screens 9, against which the flatrubber diaphragm rests.

In normal operation, the liquid passes through the inlet socket 4 andthe screen 9 into the casing and the valve sleeve 1, proceeding betweenthis and the rubber socket 6 surrounding the same to the outlet 2; Thedrop in pressure thus produced causes the rubber diaphragm 5 to movethat the return flow is blocked. At the same time the rubber diaphragmwill be lifted from the bore il in the casing and pressed against thescreen 9, so that the excess of pressure is able to escape through thisbore into atmosphere,

- which at the same time constitutesa visible in possible to performventilation with regard to any air which mayhave accumulated in theimpregnating pipe,.prior to moving the threeway cock into the positionshown in Fig. .5.

The operation of the apparatus is as follows: When the valve dis turnedto the position indicated in Fig. 4, the measuring chamber bcommunicates with the fresh water inlet pipe i and water, under tappressure, flows into and fills the ball b. This expansion -of the balltakes place freely since the discharge chamber a is in freecommunication with the outlet pipe g through valve port d. The valve dis then adjusted to its other position, thus placing the valve ports d din the positions shownin Fig. 5, i. e.'placing chambers or, D1 incommunication through the carbonating conduit e. Although conduit e isunder the high pressure of the charging gas which enters through pipe,1,

this pressure is established at both sides of the rubber ball b, andtherefore does not prevent a collapse of the ball, which collapseeffects a transfer of the measured quantity of water from the-ballchamber 17' to the outer chamber a The water is carbonated as it passesthrough the conduit e, and will be discharged from chamber 0. upon thereturn of valve (1 to the-position shown in Fig. .4. Since both chambersare subjected to the high gas pressure in the Fig. 5 position, it isapparent that there can be no difierential pressure which will preventthe filling of the ball chamber 12 when the valve is returned to theFig. 4 position. The only requirement for operation is that the freshwater be supplied to ball b, through pipes m, i and valve port d undersufficient pressure to overcome the resiliency of ball 17' eral, thenormal pressure of the city water supply system is adequate foreiiicient and rapid operation.
